Chasing 188, Super Kings top order clicked for once but the match went down the wire with the visitors reaching the target in the last ball of their innings to hand their opponents their second consecutive loss.

In a cliffhanger of a match which saw fortunes fluctuating from one side to the other, the MS Dhoni-led side was cruising along at 98 for two after 10 overs but slumped to 166 for six in the penultimate over to find themselves in a precarious position of scoring 15 from the last over off Shoaib Malik with the seventh wicket pair of S Badrinath and Manpreet Gony at the crease.

Gony held on to his nerves to hit a six and four from the first two legitimate balls before S Badrinath took a single from the last ball to stun more than 30,000 Kotla crowd.

Stephen Fleming top-scored with 44 while his opening partner S Vidyut scored 40 and Man of the Match Dhoni chipped in with a useful 33.

Earlier, Gautam Gambhir (80) smashed his fourth half-century of the tournament to lead Delhi Daredevils to a challenging 187 for five.

Gambhir held the Daredevils innings together with a 121-run third wicket stand with Shikhar Dhawan (59) to take the home team near the 200-mark after his side lost captain Virender Sehwag (23) and AB de Villiers (0) in quick succession.
